Note: A proprietary ZIP/Flate compression code (0x80b2) has been used by some software vendors. This code should be considered obsolete. The compression used by the obsolete code is identical to that defined above. We recommend that TIFF implementations recognize and read the obsolete code, but only write the official compression code (8).

The tech note already SAYS what to do....

Anything beyond that should be an option with warnings about incompatibility.
